拍星空首选彗差控制强的镜头，f/1.8光圈+边缘星点无鸟翼状彗差是核心，如20mm/24mm f/1.4定焦；变焦头收光圈到f/2.8才能保证边缘星点清晰

Unverified评估星空镜头重点看边缘全开光圈的彗差(coma)表现，边缘星点是否呈翅膀/海鸥状；优质星空镜头如三阳14mm f/2.8、适马14mm f/1.8 Art在全开即可控制彗差85% similarUnverified光圈越大彗差和边缘画质越难控制：f/1.4大光圈镜头往往需收缩到f/2.0-2.8才有干净星点，实际可用光圈优势缩水，f/1.8-2.0原生设计的星空镜头反而更实用84% similarUnverified星空拍摄标准方案：选f/2.8或更大光圈广角镜头+稳固三脚架+快门线/延时+手动对焦无穷远+关闭机身防抖；单张ISO3200-6400，堆栈降噪可拍多张后期叠加76% similarUnverified150mm口径f/5的短焦牛反在深空目视和入门深空摄影上性价比极高，但短焦比带来明显彗差，摄影若追求星点质量需额外购买彗差修正镜71% similarUnverifiedf/2.8恒定大光圈超广角变焦的定位决定了价格较高，如果主要拍摄风光且不需要大光圈（如星空），Z 14-30mm f/4 S是更轻便、可接前置滤镜且便宜的替代选择71% similar
